Convert your DC motor into a dynamo and use it to generate light without batteries. All you 
need is some capacitors, a DC motor, diode, wire, gear system and LED. To make it light all 
you need to do is spin your dynamo.

Step 1 — Infinity Light 

• The main thing you need is the gear system with one wheel and the DC motor. You need to 
put a gear on the motor shaft and attach it to the gear system as in the image. 

Step 2 

• Now we are going to build the "battery system" using capacitors. By connecting the 
capacitors in parallel (not series), we can hold more charge by using any combination of 
capacitance and quantity of capacitors. Generally, for the electrolytic capacitors used 
here, size matters. The bigger the capacitor the more charge it can hold. The capacity of 
every capacitor along with its unit of measure is marked on its case. Most common 
electrolytic capacitors are measured in microfarads ( F or MFD). 

• To make the "battery," solder all the negative pins of the capacitors together. Solder this to 
a length of wire. 

• Solder all the positive leads of the capacitors together then solder this to a length of wire.

Step 3 

• Now, we are going to connect the gear system and dynamo to the storage system. 

• Solder one diode lead to the negative terminal of the DC motor. 

• Solder the negative lead of the LED to the free diode lead from the dynamo. Don't forget to 
add the appropriate resistor for the LED. 

Step 4 

• We are finished. Now you can 
decorate it the way we want and 
use it when you want. All you need 
to do do is spin the wheel.
